Description

Technical Field

[0001] This utility model relates to the field of casting plate production, and more specifically, it relates to a device for uniformly heating the surface of a casting plate. Background Technology

[0002] Casting discs are very common in industrial production. When producing casting discs, it is often necessary to heat the surface of the discs to facilitate the addition of other processes during production. Therefore, heating devices are required to heat the surface of the casting discs. Existing heating devices generally use heating wires to heat the surface of the casting discs. During the heating process, a large amount of heat is generated. In addition to being conducted to the casting disc to heat the surface, the heat is also conducted to other spaces in the heating device, causing heat loss. This affects the heating time of the casting disc surface and results in a significant waste of energy. Furthermore, due to the weight of the casting disc and the high temperature generated during heating, it is inconvenient to remove the disc from the heating device before and during heating, thus affecting the production efficiency of casting discs.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a uniform heating device for a casting plate, which has the following beneficial effects:

[0017] 1. This utility model, by setting up a heating structure, allows the casting plate to be placed on a placement plate and positioned between the placement plate and the heating plate when heating different casting plate surfaces. Depending on the thickness of the casting plate, rotating the threaded rod causes the heating plate to descend through the threaded connection between the threaded rod and the moving block, thereby bringing the lower surface of the casting plate into contact with the placement plate and the upper surface into contact with the heating plate. By energizing the heating wire, uniform heating of the upper and lower surfaces of the casting plate is achieved, thus facilitating the heating operation of the casting plate.

[0018] 2. This utility model, by setting a connection between the cover plate and the main body box, allows the connecting frames on both sides of the placement plate to be connected to the cover plate after the casting tray is placed on the structure, through the cooperation of the first mounting post and the first mounting hole. The connecting frame on the placement plate is connected to the connecting frame on another placement plate. The placement plate and the cover plate, and the placement plates are fixedly connected by the threaded connection of the first mounting post and the first mounting piece. The extension or retraction of the electric push rod drives the heating structure and the casting tray to leave or enter the main body box, thereby facilitating the placement and removal of the casting tray before or after heating, and facilitating the production of the casting tray.

[0019] 3. This utility model, by setting a heat storage structure on the side of the main body, maintains the temperature inside the main body box during the heating process of the casting plate through the insulation plate, reducing heat loss to the outside of the main body box. The heat generated during the heating process is accumulated inside the main body box, and the heat is absorbed and stored by the heat storage plate set in the placement slot, reducing heat waste. When the casting plate is heated again, the air pump set on the extension plate pumps air into the placement slot, which contacts the heat storage plate and carries away the heat stored on the heat storage plate. The heat is then carried into the main body box through the ventilation holes opened on the main body box to preheat the space inside the main body box, thereby accelerating the heating speed of the casting plate and facilitating rapid heating and production of the casting plate.

The extension or retraction of the electric push rod 4 drives the heating structure and the casting plate to leave or enter the main body box 1. When heating different casting plate surfaces, the casting plate surface is placed on the placement plate 5 and located between the placement plate 5 and the heating plate 6. According to the thickness of the casting plate, the threaded rod 18 is rotated. Through the threaded connection between the threaded rod 18 and the moving block 20, the heating plate 6 is driven to descend, so that the lower surface of the casting plate contacts the placement plate 5 and the upper surface contacts the heating plate 6. By energizing the heating wire 7, uniform heating of the upper and lower surfaces of the casting plate is achieved.

[0035] Please refer to Figure 1-5As one implementation method for heat utilization: an extension plate 21 is fixedly installed on the side of the main body box 1, an air pump 10 is fixedly installed on the extension plate 21, the air pump 10 is connected to the placement groove 11, a second mounting post 22 is fixedly installed on the side of the main body box 1, a second mounting hole 23 is opened on the insulation plate 9, a ventilation hole 24 is opened on the side of the main body box 1 located in the placement groove 11, and multiple ventilation holes 24 are opened, the second mounting post 22 and the second mounting hole 23 cooperate with each other, a second mounting piece 25 is detachably installed on the second mounting post 22, and the second mounting piece 25 is threadedly connected to the second mounting post 22;

[0036] Specifically, during the heating process of the casting plate, the temperature inside the main body box 1 is kept warm by the insulation plate 9 to reduce heat loss to the outside of the main body box 1. The heat generated during the heating process is accumulated inside the main body box 1, and the heat is absorbed and stored by the heat storage plate 8 set in the placement slot 11 to reduce heat waste. When the casting plate is heated again, the air pump 10 set on the extension plate 21 pumps air into the placement slot 11, which contacts the heat storage plate 8 and carries away the heat stored on the heat storage plate 8. The heat is then passed through the ventilation hole 24 opened on the main body box 1 and enters the main body box 1 to preheat the space inside the main body box 1, thereby accelerating the heating speed of the casting plate.

[0037] In summary, when using it as a whole:

[0038] After the casting plate is placed on the heating structure, the connecting brackets 12 on both sides of the placement plate 5 are connected to the cover plate 2 through the cooperation of the first mounting post 15 and the first mounting hole 16. The connecting bracket 12 on the placement plate 5 is connected to the connecting bracket 12 on the other placement plate 5. The placement plate 5 and the cover plate 2, and the placement plates 5 and the placement plates 5 are fixedly connected through the threaded connection of the first mounting post 15 and the first mounting piece 17. The extension or retraction of the electric push rod 4 drives the heating structure and the casting plate to leave or enter the main body box 1.

[0039] When heating different casting discs, the casting discs are placed on the placement plate 5 and located between the placement plate 5 and the heating plate 6. Depending on the thickness of the casting disc, the threaded rod 18 is rotated, and the heating plate 6 is driven to descend through the threaded connection between the threaded rod 18 and the moving block 20, so that the lower surface of the casting disc contacts the placement plate 5 and the upper surface contacts the heating plate 6. By energizing the heating wire 7, uniform heating of the upper and lower surfaces of the casting disc is achieved.

[0040] During the heating process of the casting plate, the temperature inside the main body box 1 is kept warm by the insulation plate 9 to reduce heat loss to the outside of the main body box 1. The heat generated during the heating process is accumulated inside the main body box 1. The heat is absorbed and stored by the heat storage plate 8 set in the placement slot 11 to reduce heat waste. When the casting plate is heated again, the air pump 10 set on the extension plate 21 pumps air into the placement slot 11, which comes into contact with the heat storage plate 8. The heat stored on the heat storage plate 8 is carried away and enters the main body box 1 through the ventilation hole 24 opened on the main body box 1 to preheat the space inside the main body box 1 and accelerate the heating speed of the casting plate.
